I haven't thought about it with Little Lies, but sometimes slowing a song down gives it gravitas. Like on Youtube someone did it with Dolly Parton's Jolene and it really gave you a different feeling when you heard the song at a slower pace, with a deeper voice.

Huh... I just noticed (thanks to this slowed down version) that the intro and verse chords of Gypsy are the same exact progression as the chorus of Nightbird, one of Stevie's solo songs off Wild Heart. Just different keys (F vs C). Like, you could easily create a mashup of the two.
